Mr. O. Salvin^s Synopsis 
An examination of the type of Kaup^s S. ruficoronata at 
once shows that Prof. Baird^s views respecting it were correct 
in every way; and I propose to supply the deficiency as regards 
the name of this species by calling it Setophaga bairdi. 
Its difPerence from the true S. ruficoronata is obvious when 
the two birds are compared together. The chestnut crown of 
S. bairdi is surrounded on all sides by black_, which colour 
narrow towards the nape^ extends across the forehead. The 
whole sides of the head are also blacky with the exception of 
a ring round the eye and the lores_, which are yellow. In S, 
ruficoronata the chestnut crown meets the yellow round the 
eye and the yellow forehead without any black intervening, 
and the side of the face beneath the eye is also yellow, being 
separated from the yellow of the under surface by a very 
narrow dark line; the black patch on the nape is considerably 
larger. 
In examining a large series of S. bairdi, some specimens 
show that the black of the forehead is rather variable in 
amount; but a black superciliary streak is always present, 
and the extent of the yellow round the eye does not seem 
to exceed the amount shown in the figure (Plate VIII. fig. I). 
As regards the distribution of this species, we have no 
evidence as yet that it is found outside the limits of the 
Republic of Ecuador. Mr. Sclater included the name S. rufi¬ 
coronata in his list of the birds of Santa Ee de Bogota; but 
this must be considered to refer to the true S. ruficoronata, 
and not to the present species. 
The figure has been taken from a specimen in our collection 
obtained by Buckley at Sical, in Ecuador.
